EVALUATION BOARD SOFTWARE
INSTALLING THE SOFTWARE
The AD5663R evaluation kit includes self-installing software on
CD-ROM. The software is compatible with Microsoft®
Windows® 2000 and Windows® XP.
The software should be installed before connecting the evalua-
tion board to the PC’s USB port. This ensures that the board is
correctly recognized when connected to the PC.
1. Start the Windows operating system and insert the CD-ROM.
2. The installation software should launch automatically. If it
does not, run the setup.exe file directly from the CD.
3. After installation from the CD-ROM is complete, power up
the AD5663R evaluation board as described in the
Power
Supplies
section. Connect the board to the PC’s USB port
using the cable supplied.
4. Once the software detects the evaluation board, proceed
through any dialog boxes that appear to finalize the
installation.
